The TOP pump assembly is a one or two-stage, foot mounted pump that is designed for a trailer or stationary installation. It is designed to be driven by a hydraulic motor or jackshaft, by belt drive. The pump has an all bronze construction for the volute housing, impeller, and inducer. This construction makes the pump ideal for use in liquid oxygen service in addition to other cryogenic liquids. If the pump assembly is designed for a hydraulic motor drive, the shaft is splined. If the pump assembly is the jackshaft version, it is designed specifically for belt drive.
